Red heart guava planting and conditions, water and fertilizer management is very important

Planting conditions: planting in areas with warm climate throughout the year, the soil is required to be more fertile, and the conditions of drainage and irrigation are good. Reasonable close planting: about 90-100 plants per mu, row spacing 3m, plant spacing 2.5m. Manage water and fertilizer: in the absence of rainfall, water every 5 days, applying fertilizer at least 3-4 times a year. Pruning branches and leaves: pruning according to the principles of old, weak, sick and disabled. Flower thinning and fruit thinning: appropriate flower thinning and fruit thinning, so as not to lose nutrients.

I. planting conditions

1. Guava is a kind of tropical fruit. It is necessary to choose a good planting place before planting. It should be in areas where the climate is warmer all the year round. The best temperature can be kept at about 20-28 ℃.

2. The soil is required to be fertile, the conditions of drainage and irrigation are better, and the mountains and plains where the water source is relatively close are all fine.

Second, reasonable close planting

The main results are as follows: 1. Guava needs sufficient light when growing, so the requirements of air permeability and light transmittance between gardens are higher, and reasonable close planting is generally used when planting.

2. Generally, about 90-100 plants can be planted per mu, which can be planted reasonably according to the specific degree of soil fertility, usually according to the spacing of 3m between rows and 2.5m between plants, and can also be adjusted appropriately.

III. Management of water and fertilizer

1. Water and fertilizer management is very important in the process of guava planting, which not only determines the yield and quality of guava, but also determines the useful life of guava.

2. When planting guava, the soil needs to maintain a certain degree of humidity. if it needs to be watered every 5 days or so without rain, the watering mode can be used in the seedling stage, and sprinkler irrigation can be used when the fruit trees grow up.

3. Guava is mainly applied organic fertilizer, combined with a small amount of chemical fertilizer, at least 3-4 times a year. The amount of fertilizer can be increased according to the growth years of guava trees, and potassium fertilizer can be increased appropriately in the fruit stage. it is helpful to speed up the ripening of guava.

4. Pruning branches and leaves

1. In order to enhance the ventilation and light transmittance of the garden, the branches and leaves can be trimmed properly. if you want the yield of guava music to be high, the permeability of the garden must be good.

2. During the growth of guava seedlings, the branches and leaves in some places will grow too luxuriantly, thus affecting the light of other branches and leaves, so it needs to be pruned according to the principle of pruning old, weak, sick and disabled, so that it can reach a reasonable density. in addition, it is necessary to remove the branches properly, which is more conducive to the growth of lateral branches.

5. Thinning flowers and fruits

1. Timely thinning of flowers and fruits in the process of planting is beneficial to improve the yield and quality of guava.

2. The blooming period of guava is more prosperous, so it is necessary to carry out appropriate flower thinning at the peak of flowering period to remove some weak flowers which are damaged by diseases and insect pests and whose vitality is fragile.

3. After the flower fade, the young fruit can be thinned when the thumb is big. First, the fruit can be thinned according to the principle of retaining high-quality fruit. In addition, it may be close to the guava fruit, so it is necessary to pick some of the surrounding fruits in an appropriate amount so as not to lose nutrients.
